Papillomas or warts are usually harmless and may be removed 

 by surgical procedure. They should be removed in their entirety,

moles are sometimes pigmented with melanin, and when interfered 

 with develop into malignant melanosarcomas. Many pigmented papil- 

 lomas and papillo-fibromas are also encountered in the skin of swine, 

 while multiple fibromas have been observed, they are not at all 

 common. More rarely have primary or even secondary carcinomas and 

 epitheliomas been recorded as cutaneous tumors in swine. 



PARASITES 



Swine harbor many cutaneous parasites, some of which are ex- 

 ceedingly detrimental to the health of the animals.
